Occasionally, you might run into errors. Below are some issues players have encountered before, along with helpful guides to troubleshoot them.
Learn about other errors you might encounter, and how to troubleshoot them.
Not whitelisted error
Essential Mod uses a whitelist to make sure only friends you've invited can join your hosted world. If someone sees a message saying they’re not whitelisted, it usually means the host (that’s you!) is having trouble connecting to Mojang’s servers. A quick restart of your PC and router often helps sort it out.
Registry remapping failed, mismatched mod channel list, unknown recipe serializer or similar errors
These errors usually mean you don’t have the same mods as the host.
All players will need to have the exact same mods, including the same version of each mod.
Not an Essential user error when adding a friend
You'll need to make sure they've launched the game with the mod and have accepted the terms of service before you can add them. The best way to make sure they've done so is to have them try to add you instead since they'll need to use the mod and accept the terms to add a friend.
Timeout error when adding a friend
If you’re getting a timeout error when adding a friend, try switching it up—ask them to send you a request instead.
ICE failed error
Interactive Connectivity Establishment (ICE) failed just means your game had trouble connecting to your friend’s world. It could be caused by a bunch of things like unstable internet, strict firewall settings, or even a VPN getting in the way so it’s not always super clear what’s causing it.
If it keeps popping up, you can try restarting your PC and router first (that helps more often than you'd think). And if that doesn't do the trick, just reach out to support—we’ll help you figure out what’s going on.
Main menu issues, game freezing, missing text, or glitchy graphics
If you’re experiencing lag, have disappearing items, invisible buttons, missing text on menu boxes, the main menu not loading, weird visuals, or the game freezes (especially on the main menu or when loading a world) and you're using Intel integrated graphics, it's likely a known issue in versions 1.21.5 and up.
Mojang changed how the game handles visuals, and Intel’s drivers aren’t loving it. They are aware about the problem, but there’s no fix yet.
On a laptop with only Intel graphics? For now, the best workaround is playing on an older version. If you're on 1.21.6 or later, try 1.21.5 first. If that doesn’t work, try an even earlier version.
On a desktop? Installing a dedicated AMD or NVIDIA GPU can solve the issue.
Have a GPU but still having issues? The game might be using the wrong one. Please check Make Minecraft use your GPU.
